Description
Product Overview
The Hillman 58101 flange bearing is a precision‑engineered component crafted from high‑grade alloy steel and finished in a durable bronze coating. Designed to meet ABEC 7 standards, this bearing delivers smooth rotational performance and reduced friction, making it ideal for demanding power transmission applications. Each bearing measures 1/2 inch in outside diameter with a 3/8 inch inner diameter, and the package includes four identical units, providing flexibility for multiple installations or replacements.
Key construction details include a flanged design that simplifies mounting on shafts and housings, as well as an oil‑impregnated surface that promotes lubrication retention and extends service life. The bronze finish not only adds aesthetic appeal but also offers excellent corrosion resistance, protecting the bearing from moisture and chemical exposure in harsh industrial environments.
Usage
These flange bearings are suited for a broad spectrum of mechanical systems, ranging from conveyor rollers and gearboxes to agricultural machinery and HVAC equipment. Their robust construction allows them to handle moderate radial loads while maintaining high rotational accuracy, making them a reliable choice for both new builds and retrofits.
Installation is straightforward thanks to the integrated flange, which aligns perfectly with standard shaft diameters and mounting brackets. The oil‑impregnated alloy steel core ensures consistent performance even when operating under variable speeds or intermittent duty cycles. Users in manufacturing plants, workshops, and maintenance facilities will appreciate the ease of replacement and the reduced downtime associated with the 4‑pack configuration.

FAQ
What size shafts are compatible with the 58101 flange bearing?
The bearing features a 3/8 inch inner diameter, making it compatible with shafts ranging from 0.30 to 0.38 inches. The flanged outer diameter of 1/2 inch fits standard mounting brackets used in most industrial equipment.
Can the bearing be used with grease instead of oil?
While the bearing is oil‑impregnated for optimal performance, it can also operate with compatible greases if the application requires higher load capacity or longer service intervals. However, using grease may affect the intended low‑friction characteristics.
Is the bronze coating purely decorative or does it serve a functional purpose?
The bronze coating serves a functional role by providing corrosion resistance and a wear‑resistant surface. It also helps dissipate heat generated during operation, contributing to overall bearing longevity.
What is the expected lifespan of the Hillman 58101 bearing under normal operating conditions?
When installed correctly and maintained according to the manufacturer’s guidelines, the bearing typically lasts several years in continuous service. Exact lifespan depends on load, speed, and environmental factors such as temperature and exposure to contaminants.
Do you offer custom sizes or bulk orders for large projects?
